CVE-2020-25661

A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on...

CVE-2020-27673

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service host OS hang via a high rate of events to dom0, aka CID-e99502f76271...

CVE-2020-27673

CVE-2020-27673 is described in connected advisories as a Linux kernel race-condition bug in Xen event handling, permitting a guest (domU) to cause a denial of service or host hang in dom0 when exposed to high event rates. Affected scope: Linux kernel up to 5.9.1, used with Xen through 4.14.x. The...

usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference aka CID-056ad39ee925.

...

In the Linux kernel before 5.6.1 drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors aka CID-a246b4d54770.

...

go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel before 5.6 does not call snd_card_free for a failure path which causes a memory leak aka CID-9453264ef586.

...

fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky use-after-free which allows local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory aka CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX domain socket if the socket is being moved to a new parent directory and its old parent directory is being removed.

CVE-2020-26088

A missing CAPNETRAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a...

CVE-2020-26088

A missing CAPNETRAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a...

Design/Logic Flaw

A missing CAPNETRAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a...

CVE-2020-26088

CVE-2020-26088 affects the Linux kernel up to version 5.8.2, where a missing CAP_NET_RAW check in NFC socket creation (net/nfc/rawsock.c) could let a local attacker create raw sockets and bypass security mechanisms. This is demonstrated in multiple Nessus advisories (Unity Linux/OpenSUSE/EulerOS ...

Wrong Access Permission

Linux kernel is using wrong access permission.It can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered...

Denial Of Service (DoS)

linux is vulnerable to denial of service DoS. There is a net/ipv4/tcpinput.c signed integer overflow in tcpackupdatertt when userspace writes a very large integer to /proc/sys/net/ipv4/tcpminrttwlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6...

Use-after-free

Linux kernel has a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver, aka CID-edc4746f253d...
